根据条件动态生成wxml元素的问题 - WXOPEN Club

前端代码

<block wx:for='{{sudoku}}' wx:key='*this'>

<block wx:if='{{index%9==0}}'>

<view class='tr'>

</block>

<block wx:if='{{index%9==0}}'>

</view>

</block>

</block

js代码：

data: {

sudoku: new Array(81)

},

但这样报错，该如何实现类似功能？效果希望是这样的

换个思路的话，我会考虑把sudoku转化为二维数组，然后双重遍历，不知道是不是适用

我最后放弃了，改成如下代码方式了：

<view class='table'>

<block wx:for='{{sudoku}}' wx:key='*this'>

<block wx:if='{{index%9==0}}'>

<view class='tr line{{index/9 + 1}}'>

<view class=

'td col1 {{(index/9==0||index/9==1 || index/9==2 || index/9==6 ||index/9==7 || index/9==8)?"":"tdbg"}} {{cellSelected==index?"cell-selected":"cell"}}'

data-cell='{{index}}' bindtap='onCellClick'>0</view>

<view class=

'td col2 {{(index/9==0||index/9==1 || index/9==2 || index/9==6 ||index/9==7 || index/9==8)?"":"tdbg"}} {{cellSelected==index+1?"cell-selected":"cell"}}'

data-cell='{{index+1}}' bindtap='onCellClick'>0</view>

<view class=

'td col3 {{(index/9==0||index/9==1 || index/9==2 || index/9==6 ||index/9==7 || index/9==8)?"":"tdbg"}} {{cellSelected==index+2?"cell-selected":"cell"}}'
